In planning an industry, a financial appraisal is inevitable. As well as an agricultural business, an assessment of the building and the technologies applied to support the viability of the crop should be carried out correctly. Because of the superiority of the Discounted Cash Flow method in considering inflation and future cost changes, the payback period achieved will be closer to reality. Based on careful calculations of the proposed greenhouse with a sophisticated system and the ability to generate independent electrical energy from the sun, it was found that the discounted and non-discounted payback period can be obtained in the 14th year and 11th year respectively, with an Internal Rate of Return (IRR) greater than the loan discount rate. Moreover, the greenhouse gas emission could be cut up to 68% compared to the conventional greenhouse. Thus, for the building and its system of 25 years lifespan, this is attractive and feasible to be financed.
